Polymorphic light eruption



Polymorphic light eruption is a common skin reaction to sunlight that occurs most commonly in people with fair skin. Polymorphic light eruption results in small red raised spots and blisters on the skin within four days after exposure to ultraviolet radiation, such as from sunlight. The term polymorphic means that the skin reaction may take many different forms, although the small raised red lesions are most typical (for example, itchy, small bumps on the skin). Polymorphic light eruption is most common on the arms, but the legs and chest may also be affected. Involvement of the face is rare. Polymorphic light eruption is also termed polymorphous light eruption.
